As a regular cyclist and outdoor enthusiast, i was extremely disappointed WITH this product .Despite claims of "breathability" and "lightweight", these cycling underwear felt suffocating and heavy, leading to excessive sweating and discomfort. As a result of my tests, I determined that they were not suitable for sports and outdoors activities. The only positive was the fit which was true to size. Save your money and invest in a more high-quality, reliable product for your next adventure..See full review
